In topological insulators and topological superconductors, the discrete jump of the
topological invariant upon tuning a certain system parameter defines a topological phase …

The ground states of noninteracting fermions in one-dimension with chiral symmetry form a
class of topological band insulators, described by a topological invariant that can be related …

Critical phase transitions contain a variety of deep and universal physics and are intimately
tied to thermodynamic quantities through scaling relations. Yet, these notions are …

Topological phase transitions can be described by the theory of critical phenomena and
identified by critical exponents that define their universality classes. This is a consequence …

The investigation and characterization of topological quantum phase transition between
gapless phases is one of the recent interest of research in topological states of matter. We …

The topological properties of the Su-Schrieffer-Heeger (SSH) model in the presence of
nearest-neighbor interaction are investigated by means of a topological marker, generalized …

We demonstrate that the prototypical two-dimensional Chern insulator hosts exotic quantum
multicriticality in the presence of an appropriate periodic driving: a linear Dirac-like transition …

The notion of fidelity susceptibility, introduced within the context of quantum metric tensor,
has been an important quantity to characterize the criticality near quantum phase transitions …

Topological phases of materials are characterized by topological invariants that are
conventionally calculated by different means according to the dimension and symmetry …

We show that synthetic spin-orbit coupling for ultracold atoms in optical Raman potentials
can be exploited to build versatile quantum simulators of correlated Chern insulators …
